Abstract

The invention provides a far infrared emission film layer and a manufacturing method thereof, an electric heating disc and a cooking utensil. A mixture containing manganese dioxide, nickel sesquioxide and chromium oxide is adopted, a far infrared emission film layer is manufactured on the surface of a high-temperature 500 to 600-DEG insulated substrate, and then, the far infrared emission film layer and the insulated substrate are subjected to an annealing and film forming process to enable the far infrared emission film layer to be attached on the insulated substrate. The far infrared emission film layer manufacturing method provided by the invention is simple, the operation is convenient, the manufactured far infrared emission film layer can be matched with an electrothermal film layer for use to convert radiation thermal energy into far infrared thermal energy, rapid temperature rise is realized, the temperature lost due to moisture eliminating can be reduced, the speed of added thermal energy absorption is enhanced, thermal energy loss is reduced, the radiation thermal conduction efficiency is thus effectively improved, the energy-saving purpose is achieved, and thus, requirements on energy conservation of products by the country can be better met.

Description

Technical field [0001] The invention relates to the field of household appliances, and more specifically, to a method for manufacturing a far-infrared emitting film, a far-infrared emitting film, an electric heating plate and a cooking appliance. Background technique [0002] At present, domestic and international electric heating appliances (such as induction cookers, rice cookers and other cooking appliances) basically use traditional electric soldering wire heating technology and electromagnetic heating technology. However, the energy efficiency of electric-heat conversion of this technology is relatively low, which cannot fully satisfy the country. Energy conservation and environmental protection requirements have caused a lot of energy waste. [0003] Therefore, how to improve the electric-heat conversion energy efficiency ratio of electric heating appliances to improve the utilization rate of energy so as to better meet the national energy conservation and environmental prote...
